Building & Installing
fltk4lua is compatible with Lua 5.1 (including LuaJIT), 5.2, and
5.3, for which the required include files have to be available. You
will also need a C/C++ compiler (yes, one that actually can do both)
and FLTK version 1.3 installed. On Unixes you can probably use the
package manager for that (on Debian/Ubuntu it's libfltk1.3-dev, in
Homebrew it's plain fltk). On Windows you will need to compile FLTK
yourself (I have had success for both MinGW and MSVC++ Express 2010
using CMAKE).
The supplied Makefile is configured for Lua 5.2 on a Debian/Ubuntu
Linux system. For other Unixes or other Lua installs you will have to
change some variables in the Makefile (in particular DLL_INSTALL_DIR
and LUA_INCDIR near the top -- most other compilation settings are
determined by calling fltk-config) unless you build using LuaRocks
which will do that for you automatically. For Windows the only
supported way of building fltk4lua is via LuaRocks.
On Unix with FLTK installed system-wide a
luarocks install fltk4lua
should do the trick. On Windows you will probably have to specify the locations of FLTK header files and libraries:
luarocks install fltk4lua \
FLTK_INCDIR=/path/to/FL/incdir FLTK_LIBDIR=/path/to/fltk/libs
To install the latest version of fltk4lua from GitHub you just
clone the repository recursively and run luarocks make:
git clone https://github.com/siffiejoe/lua-fltk4lua --recursive
cd lua-fltk4lua
luarocks make
(On Windows don't forget to specify FLTK_INCDIR and FLTK_LIBDIR!)
Or you just use the dev manifest when invoking LuaRocks:
luarocks install --server=http://luarocks.org/dev fltk4lua
However, you will need a git executable installed that LuaRocks can
use (this is usually not a problem on Unix).
